The kerosene is a lighter oil. I think you would get more BTUs out of the heating oil. Just make sure that you are using the right fuel for the furnace that you have. Most now days would take heating oil.
Forced air heating
A forced air heating system uses a furnace to heat air, which is then distributed throughout the building via ductwork and vents.
Gas furnace are more energy efficient in my opinion. Electric furnaces use forced air and when you blow air over an electric element, it takes more energy to keep it hot.
Natural Gas Sometimes referred to as forced air systems, these heating systems burn natural gas, propane, oil, or use electricity to heat your home, and are the most commonly used heating systems. Air is heated in the furnace and then distributed throughout your house via ductwork.
Its because air is forced into the furnace to increase temperature. Steve.
While both furnaces and boilers fall into the category of heaters, they do have a number of noticeable differences in the way they operate. The main distinction has to with the way they distribute heat throughout your house. A furnace relies on natural gas combustion or electric resistance to generate heat. This heat is then transferred to the air via a heat exchanger and distributed via ductwork throughout your home. Furnaces are forced-air heating systems that are highly efficient and can produce a lot of heat relatively quickly. However, a system that uses ductwork to distribute heat may develop leaks, letting some heat escape and losing some of its efficiency.
Some common types of central heating systems for condos include forced air systems, radiant floor heating, and heat pumps. Forced air systems use a furnace to heat air, which is then distributed throughout the condo via ductwork. Radiant floor heating involves warm water or electric coils installed beneath the floor, heating the space from the ground up. Heat pumps use electricity to transfer heat from the outside air or ground into the condo, providing both heating and cooling.

This is called kettling and the noise is due to mineral deposits (scale) that have built up on the walls of the boiler. When the furnace heats up the water in the scale can not circulate and it boils locally (next tor the furnace wall) making the noise. A kettling boiler is not operating at peak efficiency.
